An efficient high-step-up interleaved with a common active clamp DC-DC converter for electric vehicle

This paper aims to present a high-step up and non-isolated interleaved dc-dc converter with a common active clamp circuit which makes it highly efficient. The proposed DC-DC boost converter is used as an electronic module for electric vehicle application. Due to the collection of recycled leakage energies collected in a clamp capacitor, it is then recycled to separate load by the clamp boost converter to achieve high efficiency. In addition to this, it avoids mitigation of the output diode´s reverse recovery problem and also achieves reduction of voltage stress thereby interleaving the converters. A boost converter is used to clamp the voltage stresses of all the switches in the interleaved converter which is caused by the leakage inductances.
